Disable copy-code button for mermaid diagrams

Related issues - #349497 (closed), #349892 (closed)

What does this MR do and why?

It removes the copy-code button for mermaid diagrams, fixing #349497 (closed), and potentially #349892 (closed) also.

It was added in !75433 (merged), and intended for only code blocks and not the mermaid diagrams I suppose.
